To all whom it may concern.-

Be it known that I, GEORGE JAMEs Home,

of Poplar, in the county of Middlesex, Eng.

land, have invented certain lm n'ovcnients in Apparatus for Elevatingand Discharging Grain,l\Iud, and other Materials, of which the followingis a specification.

' This invention relates to that class of elevator apparatus in whichgrabs, skips, buck- I may be forks,) of the usual form of two segmentsof a cylinder, and pivoted near their" outer edges to arectangularframe, B. Standing'up from this frame are vertical guides G C, which'are maintained in a vertical position by stay-rods C G,'secured to theangles of the frame B,fand connected together at top by a cross-hcad'These stay-rods (3 C serve not only to support the guides G C, but alsoto prevent the skips or buckets catching under the hatchway of theVessel as they are being hauled up from the hold. The two halves of theskips or buckets are drawn together by means of chains D, securedthereto near their lower meeting edges, or to a T-iron cross-stay, E, orin any'othcr convenient manner. In some kinds of materials the leveragerequired to close the ships or buckets is very great, and in that case Iprefer to secure the chains D by means of an adjustable fastening tocrossbarsE, fitted to the frame B, and carry them round pulleysconveniently secured to the cross-stays E of the skips or buckets A, asshown in Fig. 1. The upper ends of the chains 1), I attach to aslide-piece, F, which slides in the guides G O. The upwardly-projectingportion of this slide F is intended to enter a socket formed in theunder side of a second slide-piece, F, also sliding in the guides O O,and which may carry the ordinary multiplying-gear, as hereinafterexplained, or to which the hauling-chain Gr may be attached, thusforming a permanent attachment bet-ween the hauling-chain and thebucket-frame B. The

two parts F and 'F are secured together byv means of a tumbling orrocking catch or pin, 6, (shown detached .at Fig. 1%) the rounded partof which his into a notch formed in the projection of the piece F. Asthe parts F and F are brought'togetheigwhich will be effected bylowering the part F (by paying out the hauling-chain) onto the part F,which will be in the dotted position shown in Fig. 1, the projection ofF will enter the socket, strike against the flattened portion of the pina, at one side of its axial center, thereby turning the pin suificientlyto bring the flattened part of the pin into position to allow theprojection to pass it. XVhen the projection is in position, the pin willrock in the opposite dition under the influence of the counter-weight a,and the two parts F and F will be securely locked or coupled together,as shown in the drawings. As shown in Fig. l, the flattened portion ofthe pin a is about equal in length to the diameter of the projectiononthe part F, and hence' the portions of the pin which are journaled inthe part F are circular. Consequently when the slide piece or part F israised by the chain G, the downward pull of the projection on theslide-piece F has no tendency to turn the pin a, and the latter preventsthe disengagement of the parts F F as securely as would a locking pincylindric throughout its length. when the parts F F are coupled, it willbe only necessary in order to close the buckets and hoist to haul on thechain G.

The discharge of the buckets may be effected directly by the attendantat the winch,who, by means of a chain or line, c attached to thecounter-weight a and carried over the jib-head, will trip the catch orpin a at the proper time and release the piece F, and with it thebuckets, which can thus be discharged either in mid-air or on theground, as desired.

Any suitable and well-known apparatus may be employed to take up theslack of the tripping chain orline. I prefer, however, that thedischarge of the skips, buckets, or forks shall be effectedautomatically by means of a trip-lever arrangement, such as that shownat Fig. 3. This arrangement consists of a collar, 1), or itscquivale11t,which surrounds the haul.- ing-chain G, and is securedthereto at any desired point by a pin, 0, passingthroughalink of thechain. To the collar are pivoted in any convenient manner two bell-cranklevers, (I, one arm of each of which is connected with the trippingchain or line a", the other arms each having a tripping extension-piece.

At a suitable distance below the jib-head of the crane is fixed orsuspended, so as to be capable of vertical adjustment, a ring, 0,through which the trip -lever arrangement will pass as the chain G ishauled in, thepivoted extension-pieces on the arms of the bell-cranks dpermitting of such passage.

To effect their discharge the buckets will be lowered, so that thepivoted extension-pieces of the bell-cranks come intocontact with thering 0. As the lowering continues the bellcranks (Z will be turned intothe dotted position, thereby pulling 011 the tripping-chain a andtripping the catch or pin a, as before explained.

To provide for the movements above described, it is only necessary thatthe extension-pieces of the two bell-crank levers d be attached to thesaid levers by shouldered and spring actuated hinge joints of anywellknown kind,which will permit the extensionpieces to be deflectedwithout affecting the bell-crank levers as they rise through the ring 6,but which will cause the extensionpiecesto impart movement to the saidlevers as the extension-pieces come against and are arrested and movedby the ring 0 in their descent.

Instead of altering the position of the triplever arrangement on thechain G according to the level at which it is desired to discharge, thering 6, which may be supportedby chains passing'through eyebolts or overpulleys at the jib-head of the crane and'secured by tackle in anyconvenient manner, may be adjusted at any desired level for the samepurpose. By this meansthe buckets may be filled at one level anddischarged at a lower 1evela matter sometimes of great convenience.

It will be evident that the trip-lever arrangement, instead of beingmade automatic, may be actuated by an attendant on the wharf orelsewhere.

At Fig. 4 I have shown a mode of applying the ordinary multiplying-gearto my im proved apparatus. In this caseI form the sliding piece F withupwardly-projecting lugs or straps f, which slide in the guides C O, andin these lugs or straps are formed the bearings for the axles of thehoisting-drums.

It will be observed that the multiplyingdrums are outside the guides OO. I am therefore enabled to change or remove them with great facilityas desired. When the multiplying-gear is not required, themultiplying-chains will be unhooked and the main drum will be locked inany convenient manner.

The operation of multiplyinggear asiapplied to this class of apparatusis well understood, and further reference thereto will be unnecessary.

Having now described my said invention, I wish it to. be understood thatI claim- 1.
